The Browser Company of New York Inc.
2025
$488M
Why
Atlassian bought the maker of the Dia and Arc browsers to offer enterprises a browser built for SaaS and AI work, putting its products and the Teamwork Graph into the surface where knowledge workers spend most of their day.
Impact
The deal closed on October 20, 2025 at a total purchase price of $488.3 million, of which $481.5 million was cash and $6.8 million was a non-cash settlement of shares Atlassian already held. It was Atlassian's first move into the browser itself rather than apps running inside one.
Outcome
Dia and Arc continue as products while Atlassian integrates them with its platform. With DX, the two fiscal 2026 acquisitions accounted for $1.23 billion of cash paid for business combinations during the year.
